Now Dunedin's Greg Henderson has the photo to back that up.
The New Zealand cyclist pitted German cyclists Robert Forstemann and Andre Greipel against each other in a "quad off" - to determine who has the thickest quadriceps.
Henderson posted the verdict on Twitter.
"You thought Greipel has a big set of legs. There was a quad off in the German camp today. Greipel lost," he wrote.
Forstemann, 26, whose nicknames include "Mr Thigh" according to the London2012 website, is competing in men's cross-country and men's sprint.
Henderson and Greipel's Olympics both ended in disappointment, after Henderson pulled out of the road race with an upset stomach and Greipel finished 27th.
